Ventilation
Air intake
The air circulating in the passenger compartment   is   filtered   and   originates   either  
f

rom   the   outside   via   the   grille   located   at   the  
b

ase of the windscreen or from the inside in air
recirculation
 m

ode.
Air treatment
The incoming air follows various routes depending   on   the   controls   selected   by   the  
d

river:
-
 
d
irect   arrival   in   the   passenger  
c

ompartment   (air   intake),
-
 
p
assage   through   a   heating   circuit   (heating),
-
 
p
assage   through   a   cooling   circuit   (air  
c

onditioning).

The
 
air
 
distribution   can   be   varied   by   using  
m

than   one   button:   illumination   of   the  
b

utton indicates that air is distributed in that
direction;
 
no   illumination   indicates   that   air   is   not

Air conditioning On/Off
The air conditioning is designed to operate e
fficiently in all seasons, with the windows
closed.
It
  allows   you:
-

i
n summer, to lower the temperature,
-
 
i
n   winter,   above   3   °C,   to   improve   demisting.
Avoid
  prolonged   operation   of   the   air  
r

ecirculation   function   (risk   of   misting  
a

nd   of   deterioration   of   the   air   quality).
When
  the   indicator   lamp   is   off,   the   intake   of  
e

xterior   air   is   active.
When the indicator lamp is on, air recirculation
is
  activated,   the   intake   of   exterior   air   is  
in

hibited.F

P
ress this button to choose
the mode for air entry to the
passenger
 c

ompartment.
The
  intake   of   exterior   air   avoids   misting   of   the  w
indscreen   and   side   windows.
Air
  recirculation   prevents   exterior   odours  
a

nd   smoke   from   entering   the   passenger  
c

ompartment.
This
  function   also   allows   faster   heating  
o

r   cooling   of   the   air   in   the   passenger

ompartment.

When towing
Distribution of loads
F Distribute the load in the trailer so that the heaviest items are as close as possible to
the
  axle   and   the   nose   weight   approaches   the
 m

aximum   permitted   without   exceeding   it.
Air density decreases with altitude, thus
reducing
  engine   per formance.   Above  
1 0

00 metres,   the   maximum   towed   load   must  
b

e reduced by 10 % for every 1 000 metres of
altitude.
Side wind
F Take   into   account   the   increased   sensitivity  t
o   side   wind.
For more information on Weights
, refer
to   the   corresponding   section.
The   rear   parking   sensors   will   be  
d

eactivated automatically to avoid the
audible
  signal   if   a   genuine   CITROËN  
t

owbar   is   used.
Cooling
Towing a trailer on a slope increases the temperature   of   the   coolant.
As
  the   fan   is   electrically   controlled,   its   cooling  
c

apacity   is   not   dependent   on   the   engine   speed.
F
 
T
o   lower   the   engine   speed,   reduce   your  
s

peed.
The
  maximum   towed   load   on   a   long   incline  
d

epends   on   the   gradient   and   the   ambient  
t

emperature.
In
  all   cases,   keep   a   check   on   the   coolant  
t

emperature. F
 
I
f   the   warning   lamp   and   the  
S

TOP
 
warning   lamp   come   on,  
s

top the vehicle and switch off
the
  engine   as   soon   as   possible.
Braking
Towing a trailer increases the braking distance.
T o   avoid   overheating   of   the   brakes,   the   use   of  
e

ngine   braking   is   recommended.
Ty r e s
F Check  the   tyre   pressures   of   the   towing  v
ehicle   and   of   the   trailer,   observing   the  
re

commended
 p
ressures.
Lighting
F Check  the   electrical   lighting   and   signalling  o
n the trailer and the headlamp beam
height
  of   your   vehicle.
For more information on Adjusting the
headlamp beam height , refer to the
corresponding
 s

ection.

Bonnet
F Open  the   left   hand   front   door.
F  
L
ift   the   safety   catch   and   raise   the   bonnet.F
 U nclip   the   stay   from   its   housing   and   place  i
t in the support slot to hold the bonnet
open.
Opening
F Pull the release lever, located at the bottom of   the   door   aperture,   towards   you. Before
  doing   anything   under   the  
b

onnet, switch off the Stop & Start
system
  to   avoid   any   risk   of   injury  
r

esulting   from   an   automatic   change   to  
S

TART   mode.
The cooling fan may star t after switching off the engine: take care with ar ticles and
clothing that might be caught by the fan blades. Do not open the bonnet under very
windy
 c

onditions.
The location of the interior bonnet
release   lever   prevents   opening   of   the  
b

onnet when the left hand front door
is   shut.
When   the   engine   is   hot,   handle   the  
e

xterior   safety   catch   and   the   stay   with  
c

are   (risk   of   burns),   using   the   protected  
a

rea.
When   the   bonnet   is   open,   take   care   not  
t

o   damage   the   safety   catch.
Because of the presence of electrical equipment under the bonnet, it is recommended that
exposure   to   water   (rain,   washing,   ...)   be   limited.
Closing
F Take  the   stay   out   of   its   support   slot.
F  C lip   the   stay   back   into   its   housing.

Checking levels
Take care when working under the bonnet, as certain areas of the engine may be extremely hot (risk of burns) and the cooling fan could start at any   time   (even   with   the   ignition   off).
Engine oil level
The check is carried out either when the   ignition   is   switched   on   using   the  
o

il level indicator in the instrument
panel for vehicles so equipped, or
using
  the   dipstick.Checking using the dipstick
The location of the dipstick is shown in the corresponding   underbonnet   layout   view.
F
 
T
ake   the   dipstick   by   its   coloured   grip   and  
r

emove   it   completely.
F
 
W
ipe   the   end   of   the   dipstick   using   a   clean  
n

on-fluffy   cloth.
F
 
R
efit   the   dipstick   and   push   fully   down,   then  
p

ull   it   out   again   to   make   the   visual   check:  
t

he   correct   level   is   between   the   marks   A
and B .
It is normal to top-up the oil level between
two
 
services
 
(or
 
oil
 
changes).
 
CITROËN
 
r

ecommends
 
that
 
you
 
check
 
the
 
level,
 
and
 
top-
up
 
if
 
necessary,
 
every
 
3
 
000
 
miles
 
(5
 
000
 
kms).
Check
 
all
 
of
 
these
 
levels
 
regularly,
 
in
 
line
 
with
 
the
 
manufacturer's   service   schedule.   Top   them   up   if   necessary,   unless   other wise   indicated.
If
 
a
 
level
 
drops
 
significantly,
 
have
 
the
 
corresponding   system   checked   by   a   CITROËN   dealer   or   a   qualified   workshop.
To
 
ensure
 
that
 
the
 
reading
 
is
 
correct,
 
y

our
 
vehicle
 
must
 
be
 
parked

the
 
engine
 
having
 
been
 
off

or
 
more
 
than
 
30
 
minutes. A = MA X
B = MIN
If you find that the level is above the A
  mark   or  
belo

w the B   mark,   do not star t the engine.
-

I
f the level is above the MAX
 
mark   (risk
